Hi Carles,

Thank you for keeping us up to date and supporting with this topic.

I’ve added 2 more colleagues; Artem was already in contact with Pawel to add his code to Infineon github repo too.

Best regards,

Mihai

Hi Pawel,

Copying a couple of people from Infineon that might be interested in your work.

About your questions.

1. You are expected to provide the board files in a single Pull Request. If you are not able to do so maybe you can provide as much as you can using a Draft Pull Request and then ask for help in the mailing list
2. Looking at the optiga-trust-x source code, it’s licensed under the MIT license, and it’s also a cross-platform project that is not maintained as part of Zephyr. This means that the proper way to integrate it into Zephyr is to use a separate repository with a Zephyr module. See here for more details: https://docs.zephyrproject.org/latest/guides/modules.html#submitting-a-new-module
3. All code that goes into the main Zephyr repository should be Apache 2.0 licensed. The MIT license is fine for a module, which is a repository hosted under the zephyrproject-rtos GitHub organization but not the main repo itself. I recommend that you place all code under the MIT license in the external module, and the rest licensed as Apache 2.0 in the zephyr repo itself.

Hello,

I am currently working on project based on EFM32PG board and Optiga Trust X (security chip). I already did some work on implementing their framework and I run it with success with sample demo.

I want to ask about process of adding support for that board for Zephyr.

1. Do I need to do everything by my own and then do the Pull Request for that?
2. Should the framework/library be implemented as external Module or for example as external library ( /ext/lib )?
3. Is there a problem with licensing? Because this framework is build on MIT license copyrighted by Infineon Technologies and some part with MIT copyrighted by Arrow Electronics.
